Abstract
A measurement is presented of elastic deeply virtual Compton scattering γ*p → γp made using e+p collision data corresponding to a luminosity of 46.5pb-1, taken with the HI detector at HERA. The cross section is measured as a function of the photon virtuality, Q2, the invariant mass of the γ*p system, W, and for the first time, differentially in the squared momentum transfer at the proton vertex, t, in the kinematic range 2 < Q2 < 80 GeV2, 30 < W < 140 GeV and |t| < 1 GeV2. QCD based calculations at next-to-leading order using generalized parton distributions can describe the data, as can colour dipole model predictions. © Springer-Verlag/ Società Italiana di Fisica 2005.
